一、电池供电
电池供电是电脑的一种自主供电方式。大多数笔记本电脑内置可充电电池，这种电池可以在没有外接电源的情况下为电脑提供电力。当电池电量充足时，用户可以随时随地使用笔记本电脑，无需担心电源插座的问题。然而，电池供电的时间长度受电池容量和电脑能耗的影响，较短的续航时间可能是其最大的限制。
二、电源适配器供电
电源适配器供电是电脑，特别是台式电脑和某些需要稳定大功率供应的设备的常用供电方式。电源适配器通过插入墙壁插座等固定电源，为电脑提供稳定的电力供应。相比电池供电，电源适配器可以提供更为持久的电力供应和更高的功率输出，确保电脑的稳定运行。此外，许多电源适配器还具备过压、过流和短路保护等功能，保障设备的安全使用。
**Battery or Power Adapter: An Analysis of Computer Power Supply Methods**
In modern society, computers have become an indispensable tool in people's daily lives and work. To ensure the stable operation and continuous power supply of computers, there are two common power supply methods: battery power supply and power adapter power supply.

First, battery power supply. This is an autonomous power supply method for computers, with most laptops equipped with rechargeable batteries. These batteries can provide power to the computer without an external power source, allowing users to use their laptops anywhere without worrying about power sockets. However, the duration of battery power is limited by battery capacity and computer energy consumption.
Second, power adapter power supply. This is a commonly used power supply method for computers, especially for desktop computers and certain devices that require a stable and high-power supply. The power adapter provides a stable power supply for the computer by plugging into fixed power sources such as wall sockets. Compared to battery power supply, power adapter power supply can provide a longer power supply duration and higher power output, ensuring the stable operation of the computer. Additionally, many power adapters also have functions such as overvoltage, overcurrent, and short-circuit protection to ensure safe use of the equipment.
